Car being driven by my 24-year old son with completely clean drivers record near his butler university he attends on main road 38th street, indianapolis a flat stretch, at 3:00 pm at speed limit of 45 mph and 1.5 blocks ahead noticing red light went to brake to slow down and the brakes completely failed, failing to stop car, which went through the red light and into the intersection into the traffic. He was able to Dodge around the first car that would have T-boned him and sandwiched him against another but collided with a truck. Very thankful his injuries were not fatal or permanent and he remained calm and handled the car in best possible way. No red light alert on instrument panel as to anything being wrong and this car meticulously maintained at Mercedes dealership. Witnesses said also saw smoke coming from brakes. No brake function at all. Brakes perfectly normal beforehand in previous driving and in traveling from his student house that day.
